Dental erosion occurs when the outside layer of teeth, the enamel, becomes worn away by acids. Saliva plays an important protective role in remineralising and strengthening teeth after consuming small amounts of acid. However, in the presence of a lot of acid, saliva loses its protective properties to fight this acid attack. There are various sources of acids in our diet that contribute to erosion. This includes sports drinks, energy drinks, cordial, red and white wine, fruit juice, citrus fruits, fruit jams, vinegar-based foods and some salad dressings. Some signs and symptoms of erosion include sensitivity, discolouration (teeth becoming yellow), “dished out” or “cupped appearance” on the chewing surfaces of the teeth and the front teeth may look more transparent.
How can I prevent tooth erosion?
- Substitute carbonated drinks with water or plain milk (not sweetened or flavoured)
- After consuming acidic foods or drinks, rinse with water to neutralise the acids and wait at least 30 minutes before brushing your teeth
- Chew sugar-free gum to produce more saliva to remineralise your teeth
- Always use a soft toothbrush with fluoride tooth paste when brushing
- Spit, don’t rinse your toothpaste to allow the fluoride to continue to be effective and protect the teeth after brushing
- In consultation with your dentist, they may recommend various dental products to help protect the enamel further. Your dentist may also refer you to your family doctor if your acid source is related to a medical condition.
